If you really want to test the output, you need to be able to measure it. A kill-a-watt meter is up to the job. The way I do it is to get close to the 1600 VA continuous rating, then add different size incandescent lamps to the load while monitoring the output. Forget the ratings of the load devices, they're all voltage dependent. That 1875 watt hair dryer rating is at 125 volts, which the eu2000i will not be producing with that big a load. As you increase the load past 1600 VA you'll find that the output power starts trending down because the voltage goes down. My observation is that once the voltage at the the eu2000i outlet goes under 115, you've reached maximum power output. You can pull more amps by increasing the load, but the voltage will drop such the the power output goes down. With an 1875 watt hair dryer as the only load, my eu2000i outputs 122.6 volts, 14.05 amps, 1720 watts.
